You can probably find a buyer here if you subscribe.
In my opinion Yes, they are desirable.
If you were to become a Subscribing member.
You could post them in the Parts board section.
A subscription is only $0.07 cents a day for a whole year.
Then you will have the best audience of prospected buyers IMHO.
Especially if you have more parts you plan to sell
I am not trying to be Mr. Haney here.
Those seat look Good
